	Plug the arduino into the USB and you should see the backlight on the LCD come on. Turn the potentiometer to left and right and verify that the contrast changes. If it doesn't work check your wiring. Make sure the everything is connected to the correct pins.		Plug the arduino into the USB and you should see the backlight on the LCD come on. Turn the potentiometer to left and right and verify that the contrast changes. If it doesn't work check your wiring. Make sure the everything is connected to the correct pins.

			===Step 6===
			Make the data connections.

			There are 3 control pins on the LCD: RS, EN, RW and 4 data pins: D4, D5, D6, D7.
			Commands and characters are written to the LCD via the data pins. RS tell the LCD whether the data being sent is a character or a control command. EN tells the LCD that data is ready for reading. RW tells the LCD whether we want to write data to it or read data from it. Since we will always be writing data we don't have to hook the RW pin to the arduino. We simply hook it to ground.

			Here are the pins and their functions:

			RW is hooked to the ground. Each of the other 6 LCD pins get connected to a digital pin on the arduino according to this table

			There are 16 pins on the LCD numbered 1 to 16 going left to right in the breadboard picture shown below. The 5V pin on the arduino supplies the power for the backlight and the logic of the LCD display. In the breadboard picture all the wires that carry 5V are red and all the wires connected to ground are black.

			===Step 1===
			Connect the 5V and ground from the adruino to the power bus on the breadboard.

			The upper two rows in the breadboard form the power bus. All the holes on the first row are connected together under the board. Likewise, all the holes on the second row are connected together under the board.
